Blood Eruption

Choose one target you can see within range. That target makes a constitution saving throw or takes 20d10 force damage, and half as much on a success. If the creature dies to this damage their body erupts and their blood splatters on all other creatures in a 30-foot radius centered on them. Each creature in the vicinity must make a dexterity saving throw or take 10d10 damage bludgeoning, and half as much on a successful save.
